Abstract

A cooling system for an engine is disclosed. The engine has a plurality of cylinder bores which are arranged along a longitudinal axis thereof. First and second coolant passages continuously extend along the periphery of the bores on each side of the axis, from the bore located in one end of the engine to the bore located in the other end of the engine. The first and second passages are connected to each other by a connector at one end of the engine. A connecting passage is formed in each of a series of intermediate walls, which are formed between adjacent bores, for connecting the first and second passages. Water as a coolant flows from an inlet, which is formed at another end of the first passage, through, in turn, the first passage, the connector, and the second passage, and flows out from an outlet, which is formed at another end of the second passage. Also, water flows through the connecting passages.
